I've recently moved to an area with 91 octane fuel. Car is tuned for 92octane. Would it be ok to use Q16 oxygen race fuel to bumper up the octane a point or 2 using the same tune? Car is blown with supporting mods. I have a '13 5.0.
I wouldn't suggest running it, I don't know much about the fuel but I know guys that run it with carbs and they have to use a special carburetor to run it.
